INTRODUCTION European cultural norms have influenced physicians' attire in Sri Lanka. The necktie is one such item of clothing which is worn to be recognized and respected as professionals. This study was carried out to assess the perceptions of doctors and patients towards male doctors wearing neckties while providing patient care. METHODOLOGY A descriptive cross-sectional study was carried out at the National Hospital of Sri Lanka. An interviewer-administered questionnaire was used to collect data from doctors and patients. RESULTS The study included 105 doctors (57% males) and 333 patients (54% males). Mean ages of the doctors and patients were 37 years (95% C.I. 36-39) and 47 years (95% C.I. 45-49) respectively. Sixty-nine percent of the patients had completed secondary education or above. None of the patients were aware of the risk of spreading infections by wearing a necktie. Of the 41% of doctors who thought it was unnecessary to wear a necktie, 95% believed the necktie can spread infections. Ninety-five percent of patients believed doctors should wear neckties to be identified and respected and to maintain trustworthiness. CONCLUSIONS None of the patients were aware of the possible risk of spreading infections by wearing a necktie, while most of the doctors who thought neckties were unnecessary also believed neckties can spread infections. Almost all patients thought that doctors should wear a necktie to be recognized and respected. Therefore, implementing a change in dress policy for doctors is a challenging task in Sri Lanka.

The association of steatosis with serum levels of adiponectin in chronic hepatitis C (CHC) patients has also been documented. This study aimed for the evaluation of serum levels of IL28B and adiponectin as well as the association of IL28B SNPs with different clinicopathological parameters in HCV-infected patients. METHODOLOGY All 142 HCV-infected patients received peg-interferon plus ribavirin. Detection of rs8099917 and rs12979860 IL-28B genotypes was done with specific primers. Serum IL28 and adiponectin levels were measured using commercial ELISA kits. RESULTS Higher levels of both IL28 and adiponectin were found in patients. In Genotype 3a (G3a) -infected patients, IL28 and adiponectin serum levels were significantly higher than those infected with G1a. A correlation was found between increasing levels of AST and ALT in G3a-infected patients and the decrease in IL28 and adiponectin serum levels, respectively, in contrast to G1a-infected patients. Higher levels of both IL28 and adiponectin were associated with both CT allele of rs12979860 and TT allele of rs8099917 in patients in comparison with corresponding alleles in controls. CONCLUSIONS In contrast to other studies, this study showed higher serum adiponectin levels in HCV-infected patients compared to that in healthy controls. This finding is possibly due to adiponectin resistance caused by down-regulation of adiponectin receptors or tumorigenic effects of adiponectin. Our genotype-based analyses revealed, at least in part, the involvement of the viral factors in the outcome of HCV infection.

As for Lactobacillus spp., it is usually a non-pathogenic bacteria. However, it can cause infection in immunocompromised condition. In this study, Lactobacillus spp. has been isolated from the faeces of infants with Hirschsprung disease (HD), which is congenital aganglionosis of intestine, where surgical approach and antibiotics are frequently used as medical intervention. The aim of this study is to assess the antibiotic resistance pattern and determine the presence of resistance genes, if any, in Lactobacillus spp. isolated from HD infants with ileostomy. METHODOLOGY Six Lactobacillus spp. were isolated from faeces of six HD infants and confirmed using both conventional and molecular methods. Antibiotic resistance pattern was checked through disc diffusion method and was further investigated for the presence of antibiotic resistance genes (blaTEM, blaCTX-M, blaOXA-2, blaIMP, blaVIM-2, blaNDM-1 and mcr-1). RESULTS Antibiotic susceptibility of the isolates showed high level of resistance towards cephalosporins, oxacillin, aztreonam, meropenem and polymyxin group. https://www.selleckchem.com/products/thiomyristoyl.html However, four of the isolates showed the presence of blaCTX-M gene after PCR amplification. CONCLUSIONS To our knowledge, this is the first report on the presence of antibiotic resistance gene blaCTX-M in Lactobacillus spp. and this presence may pose a serious threat in treatment regimen. As not much is known regarding the presence of blaCTX-M in Lactobacillus spp., this finding may provide new light to research on antibiotic resistance in gut microflora.

Immune responses against Mtb infection involve both of types of immunity, but cellular immunity, in which certain cytokines and Th1 cells play a key role, is crucial. A better understanding of the functions of the cytokine network involved in the state and progression of TBC could identify specific molecular markers for monitoring of disease activity as well as therapy outcomes in TBC patients. METHODOLOGY We investigated expression of TNF-α, IL-6 and IRAK1 genes using an RT-qPCR technique in peripheral blood mononuclear cells of 33 TBC patients and 10 healthy individuals. RESULTS Comparison between TBC patients and healthy individuals revealed statistically significant differences for all analyzed genes. The levels of expression of TNF-α and IL-6 mRNA were higher, while the level of IRAK1 mRNA was lower in the TBC group compared to controls.
